Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMF003153 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (350 Ohms), strain range (±5%), and operating temperature range (-100°F to 350°F) must remain constant. These parameters define the gauge's measurement capability and environmental suitability.

Mechanical Specifications: Pattern type (Tee Rosette), active dimensions per section (0.125" × 0.165"), and overall pattern footprint (0.325" × 0.365") must match exactly. These dimensions ensure physical compatibility with mounting fixtures and data acquisition systems designed for the original part.

Series Classification: The CEA series designation confirms the gauge family and construction method.

Compliance Requirements: RoHS compliance and Moisture Sensitivity Level 1 status must be maintained for regulatory and reliability purposes.

The substitute part MMF403924 meets all these criteria while offering improved product status and enhanced resistance tolerance.
